Evening Troy
If you have not already done so I should check the accuracy of the rev
counter with an optical gauge.

Subject: {Spam?} Europa-List: Max RPM
Hi All,
Yesterday I took the plane out of the garage and rigged it. Started the
engine, let it warm up, and did the pneumatic carb balancing. They were
within 1/2 in.Hg of each other at 3k rpm when I proclaimed it good and
shut
it down. Is this close enough? It ran fairly smooth from 3k up to 5k.
The
gages were not so closely matched at around 2k rpm. Just wondering if
this
is normal.
When all the hoses were put back in place and vacuum gages removed,
plane
tied down securely I did a 2 minute run at max rpm, simulating a climb
to
safe landing altitude. All went well at first. However, I only got 5,200
rpm
max. The max rpm was reached without the lever being all the way
forward.
The last inch or so of lever travel produced no change. And, no the
cables
were not being pushed too far. When the lever stops in the cockpit, the
carb
lever just touches the stop. I have a 912S with the ground adjustable
Warp
Drive prop set at 17 degrees as per manual. The analog tach is made by
Mitchell and is made for Rotax. Will the rpm go as high as 5800 when the
plane is cut loose or do I need to flatten the pitch to 16 degrees and
try
it again?
Thanks again crew.
Troy
